[tarantool-patches] [PATCH 0/6] Introduce UNSIGNED type in SQL

[Nikita Pettik <korablev@tarantool.org>]

Branch: https://github.com/tarantool/tarantool/tree/np/introduce-uint
Issues:

Current patch-set allows using UNSIGNED as a column type and operating
on integer values in range up to [2^64 - 1]. This means that result of
all basic routines such as arithmetic operations and built-in functions
is extended to unsigned range.
The basic idea under the hood is separating storing positive and
negative integers into different memory cells. We've added new
type of VDBE memory - MEM_UInt. Now all positive values are stored with
featuring this flag; in turn, negative integers have MEM_Int type.
It's quite similar to MP_* format types.

For more details see content of patches.

Nikita Pettik (6):
  sql: refactor sql_atoi64()
  sql: separate VDBE memory holding positive and negative ints
  sql: refactor arithmetic operations to support unsigned ints
  sql: make built-in functions operate on unsigned values
  sql: introduce extended range for INTEGER type
  sql: allow to specify UNSIGNED column type
